  • PUs are generally prepared by polyaddition of diisocyanates and bi- or multifunctional polyols or hydroxyl terminal groups. PUs are thus multiblock copolymers of type (A-B) n , including alternating hard and soft sequences.
  • the soft flexible segments most commonly arise from polyether, polyester or polycarbonate diols.
  • the hard rigid segments most often consist of short-chain diisocyanates that impart physical crosslinking through hydrogen bonding thereby leading to higher melting temperature Tm than aliphatic polyesters or polycarbonates.
  • the macrodiols are biocompatible and biodegradable and presently easily derived from biomass.
  • PCUs Poly(carbonate-urethane)s (PCUs) without pendant hydroxyl groups have recently received some attention, although much less than poly(ester-urethane) and poly(ether-urethane).

  • Soeda et al. (Y. Soeda, K. Toshima, S. Matsumara Macromol. Biosci., 2004, 4, 721 - 728) have reported a synthesis of PCU without such NCO-reactant. This involved first the formation of a diurethanediol having a molar mass of 320 g/mol through ring- opening of TMC with hexamethylenediamine, followed by its polycondensation reaction with diethyl carbonate using a lipase along with anisole and molecular sieves.
  • both soft segments and hard units remained very short, and shorter than the length obtained when using the diisocyanate route that is typically of 1 000 g/mol up to less than 12 000 g/mol.
